3.2 MTX sheared timing pulley stud

[SuperHO]

Yup...I done broked it right good. Anyway, upon investigation I saw a threaded hole approximately 1 inch away from the tensioner hole and I'm wondering if I can use that instead of drilling out the stud and tapping a new hole. I've always wound up frocking the hole up whenever I try drilling something out, and considering this is the only block I got, I can't afford to screw it up.

Also, since It's a 3.2 block, would it be possible to use an ATX tensioner, or does that use Tue same hole as the MTX one?

Thanks!

Take a 1/2 nut, weld it to the stud back it out. Replace with new stud.

Sounds great....two problems. I don't have a welder and the stud broke off beneath the lip of the hole.

step 1.
pick up phone book or open a browser with google.

step 2.
find a 'mobile welder' in your area. explain to them what needs doing (basically what Zach said) and make sure they understand the block is still installed in the car.

step 3. pay someone to come to your house and make sure you got as much room for them to get in there and take care of it ahead of time.

step 4. stand back and let the adults handle it.

step 5. insert new stud, correctly install new tensioner, and install the rest of your shit and hope it doesn't break off again.

drilling and tapping is gonna suck because you wont really have much room to work with getting a drill in there to extract the stud or drill it out, and tap new threads. even if the stud is recessed into the hole a small amount, any competent welder shouldn't have an issue just welding a nut to the stud in there.

YMMV

Been there, done that. Solved it but acquiring a right angle drill, slowly drilling a hole in the center of the sheared stud and using an extractor. It took about 2 hours, slow going but it worked for me.

Find a welder, take it to one or have him come to you. Its out if its beneath the lip. Weld wont stick to cast iron

not unless you're doing it wrong... or right?

you can weld cast, but in this case the dissimilarity of the stud and the block should be fine.

I can't imagine it'd be that hard to find a decent welder in Michigan.
